COMBINED STEAM-GENERATOR AND RADIATOR.

SPECIFICATION forming part of Letters Patent No. 370,012, dated September 13, 1887.

Application filed January 14, 1886. Serial No. 188.597.

To all whom it may concern.-

Be it known that 1, ROBERT G. FERGUSON, a citizen of the United States, residing at Saratoga, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Combined Steam- Generators and Radiators, of which the following is a specification.

My invention relates to improvements in combined steam-generators and radiators in which a cylindrical heater and a circular shallow water-receptacle supported by the former are employed in combination with a radiator containing a narrow steam-chamber, and constructed of sheet-metal walls which are continued downward and outward to the top edges of the shallow water-receptacle and there hermetically sealed.

The object of my invention is to provide a combined steam-generator and radiator which will be portable in character, and which may be readily placed at will in any selected portion of aroom or apartment to be warmed, and by the use of only a small quantity of Water and the flame of the heater effect a generation of steam,and thereby aheating of the walls of the radiator to such a degree as to render the same capable of comfortably warming the room or apartment or the portion of the same neighboring the apparatus. I attain this object by the means illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a side elevation of the combined steam-generator and radiator, with parts broken away, exposing the interior thereof. Fig. 2 is a sectional view of the same. Fig. 3 is a plan View of the same.

The sameletters of reference refer to similar parts throughout the several views.

In the drawings, A represents aportable device, which includes the circular shallow waterreceptacle A and the sheet-metal radiator B. The water-receptacle A is made with a circular form, as shown in Fig. 3,and with a shallow depth, as shown in Figs. 1 and 2, with its bottom a and side walls a, preferably formed from a single piece. The radiator B is made with a rectangular form, and consists of the sheetmetal walls I) b,secured together at intervals (No model.)

by rivets c c, in the manner usually practiced by the trade, and contains between these walls the narrow steam-chamber shown. Thelower portion of these sheet-metal side walls b b of this radiator, as portions 1/ b, are continued downward and outward to the top edges ofthe side walls a of the circular water-receptacle, and are there secured and hermetically sealed in any suitable manner.

0 is a safety-valve, D is a steau1-gage, and E is an air-vent, all of which devices can be of any known construction, and be made to have suitable connections with the radiator B.

F is a portable heater,ofany known construc tion, and consists in its essential parts of acircular outer wall inclosing a suitable oil-receptacle, and asuitable burner, (one or more,) provided with any well-known devices for regulatin g the flame of the same. This heater operates as a portable base or support of the combined water-receptacle and radiator, and in its office as a support for the same obviates the use of legs fixed to the radiator,as heretofore, and adapts the radiator to be readily turned in either direction on the upper end of the heater,so that its flat sides can be adjusted at will to face any preferred directi0n,and at the same time, by reason of this feature of this adjustment, together with the portability of both the heater and the combined radiator and water receptacle supported at will on the former, this apparatus can be readily placed at will in any part of the room, and either in close neighborhood to the occupant or occupants or remote from them, accordingly as may be preferred for comfort.

Before using this apparatus the safety-valve will be set to blow off at the pressure intended to be the greatest on the radiator. Waterwill be introduced into receptacle A through the screw-capped opening G until it is filled about up to the upper edge of its side walls a. The burner of the heater will then be lighted,and the flame will be adjusted so as to quickly heat the water in the receptacle and convert it into steam,which will fill into all portions of the radiator and heat the walls thereof to a degree corresponding to the pressure of the steam on the same. After the pressure has been raised as high as intended to be used, the operator will adjust the flame in its volume or capacity forminga narrow steam-chamber,thesaid walls as will be most suitable for maintaining the being continued downward and outward to preferred pressure without the exercise of any the 'top edges of the shallow water-receptacle great care on the part of the occupant of the and there hermetically sealed in any'suitable I 5 5 room or other person. manner, substantially as and for the purposes Having described myinventiomwhatlclaim, and operations set forth. and deslreto secure by Letters Patent, 1s- ROBERT G.
